Yes. In number theory, two integers a and b are said to be relatively prime, mutually prime, or coprime (also spelled co-prime) if the only positive integer that evenly divides both of them is 1. That is, the only common positive factor of the two numbers is 1.

Two numbers are considered relatively prime if their GCF is 1. 4 and 9 are relatively prime.
Two numbers are relatively prime if their GCF is 1.
Yes, 46 and 87 are relatively prime. Their only common factor is 1, so that means that they are relatively prime.
No, their common factors are 1 and 11. As 1 is not their only common factor, then they are not relatively prime.
A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite. 45 and 102 are both composite.
